Remove GeForce Experience with a method in this guide to uninstalling software in Windows. I have a couple entries like that and I'd like to remove them, but the remove button is not available. But many times when you add an exe file for a game it will identify it as the wrong game. That will replace any corrupted GeForce Experience files that could be causing glitches. In the 'Manage 3D settings' of the Nvidia control panel you can add apps/games to give them custom settings. Reinstalling GeForce Experience might be a necessary potential fix for the “Unable to retrieve files” error if others fail. Select to temporarily disable the antivirus scanning for about an hour or so and then open GeForce Experience. If so, remove & restart to see if that clears the popup. See if you still have Nvidia drivers in Device Manager > Display Adapters. You can disable real-time scanning by right-clicking an antivirus tool in the Windows system tray and selecting to disable or turn it off from the context menu. The standard driver package from Nvidia includes the control panel. So, try disabling BitDefender or any other third-party antivirus software to see if that makes a difference. Those users who've confirmed that needed to disable BitDefender to resolve the issue. BitDefender Total Security is one antivirus utility widely confirmed to cause this issue. If you’ve got third-party antivirus software installed on your Windows PC, that might be blocking GeForce Experience from accessing certain folders and optimizing settings.
